I'm having my studs done in mid-June along with ITP's RR kit and was wondering about buying a used 2003 intake manifold and having it ported. What do some of you big power guys think about this? Would there be much of a gain in doing this? I'm sure there is a benefit but I'm only interested in a power benefit. Also, if I did go through with it how much could I expect to pay to have them ported? Any ideas on that. Thanks for any input and opinions guys.
